Roditi is proud to market Xeco's extensive range of high frequency fundamental (HFF) inverted mesa crystal blanks, demanded by so many of today's leading crystal and oscillator manufacturers.

HFF Inverted Mesa Blanks are manufactured from swept, pure Z growth quartz wafers using a photolithographic process and available in many shapes and forms to accommodate today's various packing styles from the mature HC range to the more recent ceramics SMD package.

Xeco's continuous R&D commitment now affords us a frequency range from the low 14MHz to 700 MHz on the fundamental, with most common angles between 35° 8’ and 35° 29 ’

This commitment has focused progress on the plated blank, which offer

• significant process savings
• improved motional control (resulting in lower spurs)
• immediate yield growth
• reduced time to market

Current HFF electroded blanks are available in

• Chrome
• Gold Chrome
• Aluminium
• Aluminium with Gold contacts
